Brocade Communications Systems 8 Reference Manual page 23

An event trap (swEventTrap, connUnitEventTrap, or swFabricWatchTrap) is basically an error
message (errShow output) that is SNMP-formatted and delivered.
FA traps
Consider enabling the FA traps if you want to use SNMP to monitor multiple connectivity units,
including Brocade switches.
The switchStatusPolicySet command determines the FA-TRAP switch status-related outputs:
•
•
•
•
The MIB-II system description swEventTrapLevel determines the output for the connUnitEventTrap.
Events in the Error Log of a severity at or above the configured threshold will generate SNMP traps.
The Fibre Alliance Trap (FA-TRAP) can be configured to send traps using the snmpConfig command.
Refer to the Fabric OS Command Reference for more information on this command.
HA traps
Consider enabling these traps to monitor field-replaceable unit (FRU) status and control processor
(CP) status when you have a Brocade director in your environment:
•
•
•
The high availability trap (HA-TRAP) can be configured to send traps using the snmpConfig
command. Refer to the Fabric OS Command Reference for more information on this command.
SW traps
There are eleven specific traps defined in Brocade SW-TRAP.
1. swfault (no longer supported)
2. swSensorScn (no longer supported)
3. swFCPortScn
4. swEventTrap

fruStatusChanged
This trap is generated by a FRU status change, such as a switch reboot or disabling or enabling
a FRU component such as (fandisable or fanenable, etc).
cpStatusChanged
This trap is generated by a change in the status of a CP, including a reboot or firmware
download.
fruHistoryTrap
This trap is generated when a FRU is added or removed. fruHistoryTrap is not generated when
standby CP is removed.
This trap is generated by a port state change.
This trap is generated by any switch event reported to the system error log.
Desired severity level is introduced to filter swEvent trap based on severity level.
